I also tried this:
3. To Restore Specific Send to Context Menu Item(s)A) Open the
SendTo folder.
B) Copy the shortcuts that you want to restore.
C) Go to the
hidden folder location below.
C:\Users\(your user-name)\AppData\Roaming\Microsoft\Windows\SendTo
D) Paste the shortcuts into your
SendTo folder, and approve.
Weird...... mailto still doesnt appear in the context menu.
for an experiment I deleted the notepad link from the send to folder, of course it disappeared from the send to context menu, I then restored the notepad link in the send to folder and of course it reappeared in the context menu.
very wierd, it must be something a lot deeper than just the folders/menu
